! { dg-do compile }
!
! Test the fix for PR87239 in which the call to the elemental function
! 'gettwo' was being added before the scalarization loop in the assignment.
! Since the result temporary was being declared in the loop body, this
! drove the gimplifier crazy. It is sufficient to compile this testcase
! since it used to ICE.
